Great idea, and thanks for the offer.
First off, StencylMUD looks awesome, you seem to be cracking the one thing I can't get my head around at all, multiplayer (and that's in any setting unity etc....) some really cool stuff you're doing there keep at it

Second, my brother was awesome, it was horrible, there's no mental health support in the uk worth a damn anymore so I'm booked on mental health first aid courses counselling courses etc, and I'm gonna do it my bloody self.
Mechanics I'm interested in :- (good idea)
Simulation level a.i. :- if rimworld is a good enough explanation great! if not I'm not going into it here.
Rendering of any sort :- wether 2d or 3d if a game has the capacity to generate it's own imagery from some kind of sample you can get a lot more game content out of small file sizes.
Procedural Map Generation :- it's still a bit the darling of games at the moment, but many titles still seem to handle it badly. I've actually build fairly robust level generators in stencyl before, but not used them for anything.
Hitpoints can do one :- In the early days of videogaming hitpoints where used to simplify the idea of taking damage, taken straight from real world games, we're still doing it now. It made sense to pass the book keeping on to computers basically leading to faster game experiences, (even the most steamlined tabletop game ain't no action rpg), but games seem to struggle to move on from a system other than effectively 70's book keeping sped up to track damage, computers can easily do more complicated stuff on the fly so they bloomin' well should.
That probably adds up to a game tbh lol.
